Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Silicosis, a preventable yet irreversible occupational lung disease, has an insidious onset with a latency period for diagnosis extending beyond 10 years from the initial exposure. The central hypothesis of this study is that silicosis cases may currently be going undetected. The long-term goal of this research is to determine the current prevalence and forecast the future prevalence of silicosis and other pneumoconiosis among working populations in Oklahoma and to assist the public health and the healthcare system in planning for a potential resurgence of silicosis.
